//	bdebug.cpp
// 
// History:
//		05/30/96 JMI	Started.
//
//		07/08/96	JMI	Now using exit(0) instead of FatalAppExit so that
//							atexit functions will get called.  Took out asm int 3
//							since I already had DebugBreak().
//
//		07/08/96	JMI	EXIT_SUCCESS now passed to exit instead of 0.
//
//		07/12/96	JMI	Removed excess param sExpr passed rspAssert.
//
//		07/16/96	JMI	Removed #if'd outness of this file in release mode.
//
//		10/18/96	JMI	szOutput in rspTrace is now static so it doesn't use
//							any stack space.  Changed str size for szOutput to
//							1024 bytes.  Changed ASSERT's string to same.
//
//		11/19/97	JMI	Added more debug output options via macros:
//							RSP_DEBUG_OUT_MESSAGEBOX, RSP_DEBUG_OUT_FILE, 
//							RSP_DEBUG_ASSERT_PASSIVE, & RSP_TRACE_LOG_NAME.
//							See below for details.
//
//		11/19/97	JMI	sSem was being decremented in the wrong spot.
//

// Does all Windows specific debug stuff.
//
//	NOTE:  Define the following Macros at the compiler settings level to get
// other than default behavior:
//
//	- RSP_DEBUG_OUT_MESSAGEBOX	-- Use an rspMsgBox() for all TRACE calls.
// - RSP_DEBUG_OUT_FILE			-- Use a file for all TRACE calls.
// - RSP_DEBUG_ASSERT_PASSIVE	-- Just TRACE (do NOT show messagebox) for all
//										ASSERT failures -- Assumes user option 'Ignore'.
// - RSP_TRACE_LOG_NAME			-- Override the default name for the TRACE log
//										file.
